Question

A company finds that on average, they use 43 minutes for each meeting.

An employee sketches a graph to show the total amount of time in minutes, T, used for m meetings. The graph shows the value of T for 1 to 5 meetings.

If the employee counts by 10's, what should be the largest value on the T-axis of his or her graph so that the scale is the most appropriate for the given information?

A. 10

B. 40

C. 50

D. 200

E. 210

F. 220

G. 250

Answer 1

Answer: 220

Explanation:

Answer 2

F. 220

Explanation:

Showing the time for 1 to 5 meetings means we would go from 43(1) = 43 to 43(5) = 215 for the y-axis (time in minutes).

We are counting by 10s. The two closest tens to 215 are 210 and 220. However, in order to show 215 on the graph, we must go up to 220.
